Electronics for New Machine + Chinese Spindle + VFD

[mturneruk]

Hear you Jazz.

So you don't think it's load related.
In that case is it possible that the VFD is generating a lot more noise when it's cutting rather than just running ?
Is the next test to take the VFD out of my enclosure?
Nightmare...

Yes it's possible but whether or not that is the problem I'm not so sure.! The easy way to check is to remove the VFD from the Control box.
The VFD cables running thru the machine shouldn't be a problem provided you have a little separation from signal cables.

Like I say this won't be load related because I've pushed cutter thru MDF without spindle running and motors not stalled before material is ripped from bed so with the small DOC and low Feed rate you have been using then it won't be load. Even with a very tired cutter it wouldn't cause this problem.!. . . Again thou easy checked just throw a new cutter in it.!!

The amps are fine at 3.8A. 2000(10x) micro steps are fine so you have no issues there.
It's not the drives protecting them selfs, they would just fault and blink at you showing what cause the fault.

Can you make it do it and video it. This may highlight some things. Also show the Electrics and wiring around machine.

Thanks Jazz. First job in the morning.

OK.

So here is a video of the problem.

If you want me to video inside the box i will.
I was racking my brains this morning and i remember something similar happening on my previous machine when jogging.
Could this possibly point to the fact that my problems are possibly connected to the PC / mach3 driver / plugin?

Cheers

I was racking my brains this morning and i remember something similar happening on my previous machine when jogging.

Common denominator being the Keyboard.? . . . Did you try changing the keyboard as I suggested.? I've had many daft happenings like this over the years and it's been keyboard related.

I think you have 2 issues really. The losing connection I'm 99% sure is noise affecting the USB.

The Jogging I'm betting is keyboard related.

1. Reinstalled Mach 3 from scratch and re-entered all my settings. Same problem.

2. Just tried a different keyboard. Same problem.

3. Purchased UCCNC as an alternative to mach 3. That's the next test.

After that i suppose i have to assume it's noise and i will have to try taking the VFD out of the box.

UCCNC seems to be fine.

I cannot get it to crash or stop and I have just run several jobs successfully. I even ventured up to 2500 mm / sec feed rate towards the end and no problems.

Weird why that should solve it.

I have to say I like UCCNC a lot. It's cleaner and has a much better interface, and is much simpler which is what i have been after. So i will keep an eye on it for now until i have some confidence it's not going to go mental on me.

Cheers Chaps. Thanks for all your help.
